Personality value: Difference between revisions

If ''p'' is even, that Pokémon has the first [[ability]] for its species. If it's odd, it has the second. If a species has only one ability while ''p'' is odd, it gets the only ability it can. Pokémon transferred from [[Generation III]] to [[Generation IV]] that can get one of the [[Generation IV#New abilities for old Pokémon|new abilities]] will retain the ability they had in Generation III; however, if they are evolved and their personality value is odd, they will get the new ability upon evolution. For example, a {{p|Porygon}} that has the ability Trace is brought to a Generation IV game. If it then evolves into {{p|Porygon2}}, it may keep Trace (if ''p'' is even), or it may switch to the ability {{a|Download}} (if ''p'' is odd). The reason this happens is because although the ability is initially determined by the personality value, the ability is stored as a separate value in the [[Pokémon data structure in Generation IV|Pokémon data]]. When the Pokémon evolves, the personality value is rechecked, and a new ability assigned (based on whatever game it is in when it evolves).
